The steppes provide important habitats for sev- eral species of cranes, including the Red-crowned Crane (Grus japonensis). I have studied the cranes in the area since 1988. The Red-crowned Crane mainly occurs in the Torey Depression (Torey Lake) and the Argun River, which represent the far western edge of the breeding area for the continental population of the Red-crowned Crane. There are some scattering records of the cranes in the Torey Depression from before 1990. The birds appeared regularly and bred from 2002-2007 at Torey Lake. There have been no records since 2008 due to the fact that the wetlands have dried out during the re- gional climate cycle in the Torey Depression. Three or four individual Red-crowned Cranes have been sighted in Argun in the early 2000's and then the numbers increased steadily until 2004. At the highest peak in 2004, there were at least 30 pairs of the cranes breeding in the wetlands of the river floodplain. Since then, with the reduced water flow in the Argun River and more and more wetlands drying out, the Red-crowned Crane population decreased dramatically to four or seven territories. The cranes are facing serious threats in the Argun River, such as frequent spring fires, poaching and water pollution. We need to unify efforts from both the Russian and Chinese sides to protect the cranes and their wet- land habitat in the area.","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129535363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This location is approximately 80 km west of Kaxgar. After experts checked the photographs, it was identified as an adult Egyptian Vulture (Neophron percnopterus), also known as the White Vulture (Fig. 1). This is the first time a Chinese bird-watcher photographed this vulture. The point of record, Wuqia County, is about 110–130 km distance from the border of Kyrgyzstan and Tajikistan. The Egyptian Vulture is found in southwestern Europe, northern Africa, south and west Asia, as well as some countries neighboring China, i.e., India, Nepal, Pakistan, Afghanistan, Tajikistan, Kyrgyzstan and Kazakhstan. This bird likes to live in groups and use old nests. This species is genetically relatively close to the Bearded Vulture or Lammergeier (Gypaetus barbatus). The Egyptian Vulture is a medium to large bird (length 56–64 cm); its entire body is white but its flight feathers are black, it has a small head with a narrow and long bill and a wedge-shaped tail (Fig. 2). They sometimes crack eggs by using a stone, a rare example in the case raptors of knowing how to use tools.","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122959315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of our research was to investigate the impact of human-caused disturbances on the Hooded Cranes. We investigated three behavior activities of the Hooded Cranes, i.e., flying time, flushing distance and the duration of vigilance. The results indicate that the auditory stimuli caused by local people provoked the most pronounced disturbances to the Hooded Crane. Human-caused disturbances not only frequently interrupt the feeding process of the cranes, but also lead to an increase of 200% in the duration of their vigilance and a significant increase in flying time from 0.4 to 0.7 h ( p < 0.05). In addition, high-intensity noise can cause larger flushing distances; foraging cranes will flush away by about 600 m when disturbed by the honking of vehicles. Whistles or shouts by local farmers in the field generated the largest sound intensity, about 120 dB, which caused a flushing distance of over 700 m. In order to reduce the negative effect of human-caused disturbances on these cranes, it is imperative to define a buffer zone around sensitive areas during the fall stopover period. To solve the conflict between the interest of farmers and the demand for crops on the part of the cranes requires financial compensation to the farmers for the crops consumed by the Hooded Crane in order to enhance the conservation of this vulnerable bird species.","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"86 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120908549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A survey of the distribution, population dynamics, flock size and behavior was conducted in Altun Mountain National Natural Reserve from September to November 2011. We investigated the size and distribution of its population in this area with a sample spot survey and by direct counting. We found Black-necked Cranes on the wetlands of Wuzunxiaoer, Yusup Aleksei, Yaziquan, Qimantag, Tula Ranch and elsewhere, where we recorded 126 individual birds of the species in Yixiekepati (37° 15′–37°23′N, 90°11′–90°20′E, elevation 3903 m), the largest population we have observed in this area. In the reserve, the population consists of about 180–200 birds. Combined with previous records, we conclude that more than 260 Black-necked Cranes live in Xinjiang. Cranes gathered conspicuously in the middle of October where the highest number of birds appeared on 29 October. All of the cranes had migrated out of this area by 6 November. Time budgets and diurnal behavior rhythms of Blacknecked Cranes were observed in the Yixiekepati wetland at daylight (from 06:00 to 18:00). Foraging was the most prevalent type of behavior during the autumn period, accounting for 58.9% of the diurnal time budget, followed by preening (13.2%), vigilance (9.5%), walking (8.2%), flying (3.5%), resting (3.4%), chirping (2.7%) and other types of behavior (0.6%).","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123790218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our surveys confirm that Zhigatse Prefecture is the most important wintering area for the species, accounting in some years for as much as 39% of the estimated world population. Counts ranged from a high of 4240 cranes in Jan- uary 2007 to a low of 2636 in February 2009. Chick recruitment (chicks/100 cranes) ranged from 8.2 (January 2010) to 11.3 (January 2007). The highest concentration of cranes during all three surveys occurred on the 60 km stretch of the Yarlung Tsangpo (River) between Lhaze and Phuntsoling. To evaluate potential impacts of the Xietongmen Copper Mine, we monitored wintering crane numbers prior to mine installation in an intensive study area located between the Shab Chu Valley and the city of Zhigatse. Our surveys recorded on average 820 ± 83 cranes (SE; n = 8) in this area. With the instal- lation of the mine at a location ~50 km west of Zhigatse, increased traffic and development on the north side of the Yarlung River will likely result in a shift in crane distribution away from the north side, to nearby suitable habitats. Based on our survey results, we recommend three areas hosting high numbers of cranes in the vicinity of the mine be added to the Yarlung Tsangpo Middle Reaches Black- necked Crane Nature Reserve. These areas are Nierixiong and Jiaqingze Villages in Nierixiong Xiang and the Shab Chu Valley.","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130819479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two crane surveys were conducted at Poyang Lake during the 2011/2012 winter, the first on 18–19 December 2011 and the second on 18–19 February 2012. The survey covered the entire Poyang Lake basin, as well as two main lakes in Jiujiang (Saicheng Hu and Chi Hu), i.e., a total of 85 sub-lakes were surveyed. Both surveys recorded four species of cranes. The first survey on 18–19 December 2011 recorded 4577 Siberian Cranes (Grus leucogeranus), mostly in Bang Hu, Sha Hu and Dahu Chi, 302 Hooded Cranes (G. monacha), 885 White-naped Cranes (G. vipio) and 8408 Eurasian Cranes (G. grus), for the most part in the center of the lake basin. The second survey on 18–19 February 2012 recorded 3335 Siberian Cranes (mostly in Poyang Lake National Nature Reserve (PLNR) and its surrounding areas), 110 Hooded Cranes (largely in PLNR and its surrounding areas), 283 White-naped Cranes (86% in Bang Hu) and 2205 Eurasian Cranes (particularly in Duchang and Nanjishan NNR). The number of Siberian Cranes enumerated in December was 1000 more than the second count in February 2012. It is not possible to rule out double counting due to the close proximity of the main sites of the Siberian Cranes. During winters from 1998 to 2009, the average of the highest counts each winter was 3091, ranging from 2345 in 1996 to 4004 in 2002. By comparison with counts taken at other times, we therefore estimate a wintering population of Siberian Cranes of ~3800–4000 at Poyang Lake. Additional evidence will be needed to raise the world population estimate. Our more recent surveys indicate a continuing decline in the number of White-naped Cranes and an increase in Eurasian Cranes.","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121259951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although this species has received much attention by scientists, conservationists and the general public, the continental population of the Red-crowned Crane continues to face serious threats which affect not only its population dynamics but also its breeding and wintering habitats. Habitat loss and deterioration are the main causes of the decline of its population. With the massive loss of habitats in all parts of its range ― breeding, stopover and wintering grounds ― the cranes have been forced into crops and farmlands where cranes are more vulnerable to human activities, such as poisoning the cranes and conflicts with farmers. From our review of studies done over 30 years, the eastern flyway subpopulation has been stable or slightly increasing and the western flyway subpopulation of the Red-crowned Crane has sharply declined in recent years. The wintering population for the western flyway has declined from over 1100 to less than 500 birds. Not only is the size of the population reduced to less than 50%, but most recently the decline has occurred with frightening speed, by 50- 150 birds per winter. The current wintering range for the west flyway is only about 8% of its extent in the 1980s. Urgent actions for habitat protection, law enforcement and education need to stop the declining trend for this species.","PeriodicalId":227522,"journal":{"name":"Chinese Birds","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131101131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
